Counterintuitive Properties of High Dimensional Space (2018)
Our geometric intuition developed in our three-dimensional world often fails us in higher dimensions. Many properties of even simple objects, such as higher dimensional analogs of cubes and spheres, are very counterintuitive. Below we discuss just a few of these properties in an attempt to convey some of the weirdness…

CRLF is obsolete and should be abolished
It seems that (1) there is still more software in circulation that depends on archaic CRLF line endings than I originally thought and (2) many people do not share my enthusiasm for creating a CRLF-free world. Alas. This makes me sad, but it is what it is. Thanks to everyone who was willing to give the idea a test run…

Defining Statistical Models in Jax?
This is Bob. And I’d like to know the best way for us to code a bunch of models in JAX to use to evaluate parallel algorithms including normalizing flows. I’m going to dump out my current thinking, but I’m really hoping to get feedback from experts on the best way to do this without starting a flame war in the…

Lessons learned from profiling an algorithm in Rust
Recently, I've been working on a new approximate nearest neighbor search algorithm called RaBitQ . The author has already provided a C++ implementation that runs quite fast. I tried to rewrite it in Rust (yet another RiiR). But I found that my implementation is much slower than the original one. Here is how I improve…

A dictionary of single-letter variable names
Haskell’s expressive type system means that type signatures can carry a lot of information. Haskell’s polymorphism means that you sometimes write functions that work across an enormous range of types, and are left wondering “what do I actually call my variables?”. It is often the case that there’s nothing to say…
